Status: OUT
The GoF's fully grounded unified design methodology — system-level coherence backed by both spatiotemporal infrastructure and LSP type governance — achieves verified formal correctness only when behavioral subtyping is decidable for the domain's type hierarchy.
Depth-11 — the methodology's double grounding depends on LSP's type governance, which in turn depends on verifiability of behavioral subtyping; undecidability limits formal verification without invalidating the methodology's practical value
